Open the file in g-spot and confirm that you have two audio tracks. Many dual language videos have only one track, with different languages in each channel.

If you only have one audio track then you need to demux the audio out to a stereo wav file, open it in something like audacity, copy the channel you want over the one you don't, save the results, then remux the files back together using muxman.

If it has two audio tracks, you can use rejig to grab just the video track and the audio track you want, and mux man to put them together for a single file.
